A 3 Claims. (Cl. 62-1085) Our invention relates to a device intended for household refrigerators and the main object thereof is to provide means for making icicles or long narrow sticks of ice for convenient use in thermos and other bottles or the like in preference of the now prevalent ice cubes or crushed ice for insertion through the narrow necks of the bottles. It is believed that such a contrivance would be welcome as an addition to refrigerators in all homes.

It should be noted that this freezing mold or tray is shaped so that it can be used in ordinary refrigerating units.

This ice stick mold or double tray is very easy 1 to handle and each tray can be used singly or both trays together as they will come apart easily being separated by a metal dividing plate.

The formed ice sticks can be readily removed from the trays in the usual manner by application of water, and no waste will occur.

In the accompanying drawing, one embodiment is illustrated, and

Figure 1 shows in top plan view both trays assembled. I

Figure 2 is a transverse section in larger scale taken along line 2-2 of Figure 1.

Figure 3 is a top plan view of the bottom tray with the cover or dividing plate partially removed.

Figure 4 shows a fragmentary vertical length section of the top tray.

As best shown in Figures 2 and 4, the invention consists of a top tray l and a bottom tray H the one fitting snugly in the other and being adapted to be placed singly or both together in the ordinary ice pan of a refrigerator.

The top or upper tray l0 preferably made entirely of rubber or similar plastic material and cast or pressed in on piece, built on a full length bottom 9, has three chambers formed by a front and a rear transom l2, l3 of the same or different lengths varying preferably between 3 /2 and 4 inches. Each of said chambers contains several compartments l4, 9 being indicated on the drawing, of the same width, about inch and inch depth and are separated by the partitions l5 extending the entire length of each chamber. These sizes may vary to suit conditions. These partitions, transoms and bottom are molded as a unit with a rolled edge or bead IS on all four sides at the top edge. The side walls l8 and the rear end wall I 9 are all perpendicular to the bottom 9, but the front wall 20, Figure 4, is preferably inclined at a 70 angle against the bottom 9, this for the purpose of 2 facilitating removal of the top tray in from the bottom tray ll.

The bottom tray l I is likewise preferably made entirely of rubber built up on its flat bottom 23 with perpendicular side and rear walls 24, offset near the upper edge to form a flat seat or shelf 2'! to accommodate the bottom of the top tray [0. The edge is finished off with a bead 26 similar to the top tray and this bead facilitates the removal of the bottom tray ith or without the top tray.

A vertical length section is shown in Figure 4 of the top tray indicating the perpendicular rear wall l9 and the slanting front wall 20 having an inclination of about against the bottom 9. When the top and bottom trays are assembled as in Figure 2 a flat dividing plate 30 of aluminum or other metal is inserted between them, entirely filling the seat 21 of the lower tray II and on this plate the top tray rests. Its function, being a good heat conductor, is to speed up the freezing action on the water in the trays, which, when made of rubber or similar plastic material, are inferior heat conductors. A finger hold 3| is shown at the front edge of the plate consisting of a cut-out of its edge. However, the trays may be made entirely of metal, in which case any dividing plate 30 would be superfluous.

The bottom tray is arranged with chambers and compartments I4 similarly to the top tray and accordingly provided with transoms l3, and longitudinal partitions l5. Both trays together may therefore produce 51 or more sticks of ice.

It is to be understood that the invention as here disclosed is not limited to the details here described and shown but that the same may be varied without departing from the spirit of the invention as defined by the subjoined claims.

We claim:

1. A freezing mold for producing ice sticks in refrigerators, comprising a top tray and a bottom tray, each forming a separate unit and made of resilient material; each of said trays having a flat bottom, surrounding side walls, transoms and length partitions providing a plurality of long, narrow compartments wherein to produce the ice sticks; said bottom tray having a shelf-like formation having an upstanding vertical edge extending along the four walls adapted for seating the top tray therein, a removable metal plate inserted on aid shelf like formation beneath the top tray, the function of said plate being to increase the freezing ability of the mold.

2. A freezing mold for producing ice sticks in refrigerators, comprising a resilient top tray and a resilient bottom tray each forming a separate unit; each of said trays having a flat bottom, surrounding side walls, transoms and length partitions providing a plurality of long, narrow compartments wherein to produce the ice sticks; said bottom tray having a shelf-like formation extending along the four walls adapted for seating the top tray, a removable metal plate inserted on said formation beneath the top tray, the function of said plate being to increase the freezing ability of the mold, the top edges of the side walls being turned to form a bead to facilitate lifting of the trays.

3. A freezing mold for use in refrigerators comprising a resilient top tray and a resilient bottom tray, each of said trays having a bottom and side walls, transoms and partitions providing a plurality of compartments, said bottom tray in- REFERENCES CITED The following references are of record in the file of this patent:
